Energy coefficients for comparison of aircraft supported by different propulsion systems

Energy coefficients for comparison of aircraft supported by different propulsion systems

Stakeholders envision introduction of electric and hybrid-electric aircraft into operation by 2035. First developments meet a series of challenges caused mostly by deficiencies (like low specific energy) of battery technology. Due to this, electric aircraft will have unacceptably large take-off...

Constraint guided search for aircraft sequencing

Constraint guided search for aircraft sequencing

Aircraft sequencing problem (ASP) is an NP-Hard problem. We use the constraint and the objective functions to obtain such problem specific knowledge and we exploit such knowledge both in a constructive search method and in a local search method. We...

Material failure analysis and engine combustion instabilities of both air and non-air breathing engines

Material failure analysis and engine combustion instabilities of both air and non-air breathing engines

Along with material failure aircraft engines, also suffer from combustion instabilities which result in loss of fuel and sometimes accidents. Both air-breathing and non-air breathing engines have one thing in common and that is combustion instabilities. This p...

Factors affecting passenger choice of low cost carriers: An analytic network process approach

Factors affecting passenger choice of low cost carriers: An analytic network process approach

Although the literature has contributed to identifying various influences on passenger choice of low-cost carriers (LCCs), the evaluation of the relative importance of these factors has not been empirically determined. In their decision about choices of LCCs, ...

Price setting for extra-baggage service for a combination carrier using the newsvendor setup

Price setting for extra-baggage service for a combination carrier using the newsvendor setup

Wide-body aircraft are frequently used to meet upsurges in passenger demand, resulting in the underutilization of the belly-hold capacity on many routes. In the existing literature, investigating this specific underutilization problem has not received much att...
